RADIATO R.

SPECIFECATION forming part of Letters Patent No. 319,230, dated June 2, 1885.

Application filed December ll, 1884. (No model.)

' be quick and effective in action.

The invention consists in the particular constructions and combinations of parts of the radiator, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a radiator constructed in accordance with my invention, and with one of the radiator-tubes and part of the base in section. Fig. 2 is a plan view with one of the radiator-tubes in horizontal section. Fig. 3 is a transverse section of the base and tube connections, and with the tube in section on the line as m, Fig. 4. Fig. 4 is an enlarged sectional plan view through the sheet-metal radiator-tube, and Figs. 5 and 6 are sectional plan views of modified constructions of sheetmetal radiator-tubes.

The letter A indicates the cast-metal hollow base of the radiator, which is tapped at opposite ends to receive the valved supply and return pipes 13 0, respectively, and at intervals along its top the base A has screw-nipples,or is tapped to receive the ends of the tapering cast-metal connections D, which have grooves d d in their upper edges, corresponding in shape to the cross-sectional form of the inner and outer sheet-metal pipes, E F, respectively, which form the main parts of each radiatortube, and are soldered or otherwise made fast in the grooves d d of connections D. I pre- -fer to make the inner air-circulating pipe, E, in the corrugated or stellate cross-sectional form,(represented in Figs. 2, 4, and 5,) and to make the outer pipe,F, in cylindrical form, as shown in Figs-2 and 4.. The corrugated form of the inner pipe, E, presents a large heat-radiating surface to the air passing through the interior space, 6, of thepipe, and also presents a correspondingly large surface to be heated by the steam, hot water, or other heating agent which circulates in the space f, between the corrugated wall of the pipe E and the cylindrical wall of the outer pipe, F.

Within the pipe E, I fasten, at suitable points, to the bases of the corrugations of the pipe the braces G, preferably three in number, and which prevent collapse or distention of the pipe.

To the top of the radiator-tubes I fit caps II, which have grooves h h, into which the upper ends of the pipes E F are tightly soldered or brazed, or otherwise suitably fastened, and the caps have openings I, through which the heated air rising from the pipe E may escape to the room. Passages J in the connection D open into the space f, and into the base A, to admit the steam or heating agent to each of the radiator-tubes, and passages K in the connection D communicate with the interior air-space,e, so that the air to be heated within the pipe E may pass freely through said passages K to the space 0, either from the room in which the radiator is placed or from pipes M, screwed to nipples L,'and leading to the outer air at any convenient points. Fresh-air pipes M may connect with passages K at one or both sides of the radiator, and when the pipes M are not desired the nipples L may be dispensed with, as indicated by the dotted lines at m m in Fig. 3. It is evident that the thinmetal of the pipes E F will very quickly be heated by the steam or hot water entering the space f between the pipes from the base A, and that the air sur rounding the outer pipe, F, and the air passing through openings K to the interior of the pipe E will quickly be heated and discharged into the room and the air of the room will have a freer circulation, and when the airpipes M are used the apartment will be supplied with pure warmed air, conducive to the most perfect ventilation.

I propose to make all parts of the radiatortubes and their base-connectionsinterchangeable, so that radiators having any desired number of tubes maybe built upon their bases with facility, and so that repairs and renewals may be made quickly and cheaply at any time. The pipesE F may be made of asingle sheet of metal bent to shape, and riveted, sol

dered, brazed, or otherwise fastened at the joint. I 1

Among the advantages of my radiator may be named its cheapness, lightness to haul and erect, a saving of time in its erection, the large heat-radiating surface in a small space, and the tubes present a smooth outside surface on which dust will not easily settle, and which may receive either plain or elaborate decoration, and-they heat an apartment more quickly than the cast or wrought metal radiators, and because of the thinness of the tubes the circulation of heated air is quickened to an extent which allows-the heating of apartments with less area of the tubes than is required in ordinary radiators.

I do not limit myself to the cross-sectional form of the pipes E F, as represented in Figs. 2 and 4, as an inner corrugated pipe, E, and an outer corrugated pipe, F, forming the airspace c and sinuous space f, for the steam or hot water, may be used with correspondinglyarranged connections to the base, and a head piece or cap, and with central braces, G, and braces 9 between the two pipes, as shown in Fig. 5; or the radiator-tube may consist of a cylindrical inner pipe E and a corrugated or stellate outer pipe, F", suitably braced to each other at G and providing an inner air-space, c and outer steam or hot-water space, as represented in Fig. 6; but the construction shown in Figs. 1, 2, 3, and 4, and hereinbe fore particularly described, is preferred.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, in a radiator, of the hollow base A and one or more heat-radiating tubes, consisting of a connection, D, having independent passages J K, sheet-meta1 pipes F F, providing. an air-space, e, and a space, f, for the heating agent, and a cap or head plate, H, closing the space f, and having openings I, substantially as herein set forth.

The combination, in a radiator, of the hollow base A and one or more heat-radiating tubes, consisting of a connection, D, having-independent passages J K, an inner sheetmetal pipe, E, having a corrugated or stellate cross-sectional form, an outer sheet-metal pipe, F, and a cap, H, closing the top ofpipe F, and having openings I, substantially as herein set forth.

3. Aradiator-tube consisting of a cast-metal -base-connection, D, having passages J K, in-

ner corrugated sheet-metal air-pipe, E, outer sheet-metal pipe, F, and a cap, H, having openings I, substantially as herein set forth.

4. A radiatortube consisting of a cast-metal baseconnection, D, having passages J K, inner corrugated sheet-metal air-pipe, E, outer sheet-metal pipe, F, a cap, H, having openings I, and the braces G within the pipe E, substantially as herein set forth.

5. A radiator-tube constructed with an inner sheet-metal air-circulation pipe, and an outer sheet-metal pipe for the heating agent, a cast-metal base-connection, D, having independent passages J K, and a cap, H, having openings I, and said parts D H having grooves d h, respectively, to receive the ends of the sheet-metal pipes, substantially as herein set forth.
